摘要：

As a remarkable structure, 2D magnetic heterojunctions have attracted researchers' attention owing to their controlled manipulation in the electronic device. However, successful fabrication as well as modulation of their structure and compound remain challenging. Herein, a novel method is designed to obtain a CoCl2/Co3O4 heterojunction on Si/SiO2 substrate with the assistance of supercritical CO2 (SC CO2), and the as-fabricated sample has significantly increased coercivity and saturation magnetization, which is 11 times higher than pure Co3O4. Further, it can be found that the CO2 pressure has the decisive effect on the saturation magnetization of the sample. Therefore, it suggests that the tunable electronic-magnetic device can be anticipated to be obtained in the future.
